Description
Technical field
The present invention relates to a kind of motor test run methods.
Background technique
Currently, there are the electrical equipments of a large amount of low pressure (exchange 380V) motor type in industrial circle.According to phase
Close regulation, such motor needs to carry out following three kinds of test runs before normal use: (1) test run of switchgear (drawer) testing position,
(2) switchgear (drawer) operating position solo test run and (3) switchgear (drawer) operating position linkage trial run.Wherein, switchgear
The main purpose of testing position test run function is the correctness that control circuit acts in detection switch cabinet；The examination of operating position single machine
The main purpose of vehicle function is to detect the break-make situation of main circuit power and the rotation direction and water cycle test of motor；Work
The main purpose for making position linkage trial run function is to detect the correctness of gauge external signalizing activity.When total Test is completed just
It can operate normally.Debugging detection protection act correctness herein is not emphasis of the present invention, therefore in the present invention
In the function is not specifically described.In addition, mutually speaking on somebody's behalf since the driving of gauge external is on testing without influence in of the invention
The problem of instrument starting signal will not be described in detail further in bright.
For conventional test run mode is described in detail, conventional examination is illustrated by taking conventional hardwire control circuit as an example in Fig. 1
Vehicle mode.In Fig. 1, QA is breaker auxiliary contact (breaker auxiliary contact in switch cabinet drawer i.e. above)；SW1 is
The testing position contact of drawer；SB1, SB2 be scene open/stop button；SBT1, SBT2 be drawer on open/stop button；Y1 is
Instrument (distribution type control system DCS) allows start signal contact；K2 is instrument DCS interlock shutdown signal contact.Control electricity
Road may be implemented motor at the scene position driven, shut-down operation, can also realize distant place instrument interlock shutdown operate.
For security consideration, the driving operation of section motor " is allowed to start " control of signal by instrument.It needs herein
Illustrate, the control signal of not all motor has required " allowing to start " signal.Specifically, do not meeting
Under conditions of certain, instrument does not allow motor to drive, and " allowing to start " signal (contact) of instrument is to disconnect at this time.When full
After foot requires, which drives to instruct just effective.In the case where " allowing to start " semaphore request there are instrument, no matter
It is under which kind of test run mode of foregoing description, only after " allowing to start " signal contact closure, while other conditions are also full
When foot requires, instruction of driving could effectively.There are mechanical interlocking requirement, the test run to motor is electronic
What arbor and main shaft carried out in the case where disengaging.
Such as, it is generally the case that express pump is furnished with auxiliary oil pump.Oil pressure is detected when manually booting the auxiliary oil pump and working as
It, could scene starting high speed after reaching setting value (after meeting the requirement, instrument DCS issues the instruction for allowing to start express pump)
Pump.
As seen from Figure 1, in testing position test run, SW1 is connected, QA, Y1 and K2 access failure, need to make at this time QA,
Y1 and K2 carries out being shorted just to can be carried out out/stop on terminal operating.In operating position when solo test run, QA is connected, and is needed it
The preceding shorting stub in testing position test run for being shorted QA is removed, but Y1 and K2 access failure is (because in running-in period instrument
Work not yet complete), there is still a need for carry out Y1 and K2 on terminal to be shorted just can be carried out out/stopping and operate at this time.In working position
It then needs to be used in operating position solo test run before when setting linkage trial run to make the shorting stub of Y1 and K2 short circuit from terminal
It removes, it just can be with experiment opening/stop and interlock shutdown operation.
As can be seen from the above description, when carrying out above-mentioned three kinds of test run modes, due in conventional hardwire control circuit
Breaker auxiliary in " allowing to start " contact Y1, " interlock shutdown " contact K2 and the switch cabinet drawer that instrument DCS is introduced into connects
Point QA is accessed in control circuit.Specifically, in conventional test run mode, in testing position test run, these three contacts
Be to disconnect, therefore cannot achieve driving and shut-down operation, and in operating position solo test run, " allowing to start " contact and
The signal that " interlock shutdown " contact is connected does not have also, therefore contact is also to disconnect, and can not also be operated.
In order to realize the test run under both states, it is necessary to these contacts are shorted on switchgear terminal,
It needs for these to be shorted again when linkage trial run in operating position and remove.But due to before carrying out test run, switchgear band
Electricity, therefore carry out these operations on the switchgear of electrification and may have security risk.Moreover, these test runs operation may be into
It goes more than once, even if may also need to carry out test run operation after the completion of electronic machine overhauling.In this situation it is desirable to repeatedly
Work is shorted and removed on switchgear terminal, may be made the screw stripped thread of switchgear terminal in this way and be caused virtual connection existing
As to make control circuit cisco unity malfunction.In addition it also needs to guarantee to be shorted when carrying out above-mentioned conventional test run and operating
Correctness.It is asked so above-mentioned conventional test run mode is there are safety operation problem, debug time is long and debugging work load is big
Topic.
For using logic control motor, if not designing test run logic, can similarly there is a problem of more than.?
This, test run logical AND test run mode be it is corresponding, i.e. three kinds of test run modes will be there are three types of test run logic, wherein operating position
Linkage trial run is also final operation logic.
In the technical solution for solving the problems, such as test run using control logic in the prior art, three kinds of examinations are usually respectively adopted

Illustrate the content of driving logic judgment condition with reference to the control logic figure in Fig. 2, wherein contactor auxiliary contact
KM (operation feedback signal), breaker auxiliary contact QA, motor protector FH logic circuit be that every motor all has
Condition, instrument interlock shutdown signal contact K2 and instrument allow start signal contact Y1 be required according to specific control it is additional
Driving logical condition, that is, just participate in control logic when needing.The following specifically describes these Rule of judgment in various test run moulds
During the logic control for how meeting control requirement under formula, it is assumed that the guarantor's protection of FH horse is normal not operating and runs feedback signal KM
At dead ship condition (i.e. output high level 1):
1. testing position test run: since breaker auxiliary contact QA is in open position, do not need at this time to instrument signal into
Row test, works out a kind of testing position test run logic in the control logic method of the prior art, and breaker auxiliary in Fig. 2 is connect
Point QA, instrument have reformed into examination after allowing the logic circuit of start signal contact Y1 and instrument interlock shutdown signal contact K2 to cancel
Test position test run logic.
2. operating position solo test run: breaker auxiliary contact QA is not needed in on-state to instrument signal yet at this time
It is tested, a kind of operating position solo test run logic is worked out in the control logic method of the prior art, instrument in Fig. 2 is permitted
Perhaps the logic circuit of start signal contact Y1 and instrument interlock shutdown signal contact K2 have reformed into operating position single machine after cancelling
Test run logic.
3. operating position linkage trial run (final operation logic): breaker auxiliary contact QA is in on-state, Fig. 2 at this time
In instrument allow start signal contact Y1 and instrument interlock shutdown signal contact K2 logic circuit participate in logic control, work as nothing
It, will be there are many corresponding control when instrument allows start signal contact Y1 or instrument interlock shutdown signal contact K2 control to require
Logic completes control function.
However in the method, the test run function of three kinds of different test run modes is completed by different control logics, though
So solve the problems, such as that docking point is shorted and is removed in traditional test run mode, but since control logic is too many, so in electricity
Call the operation of these logics in actual operation can be very complicated in motivation protection panels.
